UNITED STATES PATENT OFFICE.

ALFRED LANGDON, OF JEFFERSON CITY, MISSOURI, ASSIGNOR OF ONE THIRD TOHENRY C. INMAN, OF SAME PLACE.

APPARATUS FOR MAKlNG GAS.

EPECIFICATION forming part of Letters Patent No. 360,533, dated April 5,1887.

Application filed September 8, 1886. Serial No. 213,011. (No model.)

To all whom it may concern.-

Be it known that I, ALFRED Lanonou, a citizen of the United States,residing at Jefferson City, in the county of Cole, State of Missouri,have invented certain new and useful Improvements in Apparatus forMaking Gas, of which the following is a specification,

. reference being had therein to theaccompanywill be particularlypointed out in the claims.

Referring to the drawing,which is a side elevation of the apparatus withportions in sec tion, A represents a suitable frame-work, in which ismounted a shaft, B, provided at one end with an ordinary loose anddriving pulley, B B, respectively, and at the other end with a disk orcrank, B, upon the wristpin of which is mounted a connecting-rod, B,suitably coupled with a piston-rod, 0, attached to a piston-head, C,which is adapted to fit 0. cylinder, D, having at its upper end innerand outer check-valves, D D respectively, and a similar pair of valves,D D, at its lower end. These valves are so mounted that uponadownwardstroke of the piston the upper inletvalve, D, and the loweroutlet-valve, D, are opened,while at an upward stroke of the piston-headthe upper outletvalve, D", and the lower inlet valve, D, are opened.

The inlet-valves are made to communicate witha water tank, E, the uppervalve doing this by means of thepipe F. Ashort pipe, F, extends from thelower inlet-valve into the water-tank, and both pipes terminate justabove the diaphragm E, which is perforated, as

' shown.

of the water is maintained at or near, or it may be in contact with, theperforated diaphragm E. top of the tank, to admit air into the upperportion thereof.

A pipe, I, communicates at its ends with the upper and loweroutlet-valves of the cylinder, and is provided with a T- coupling, J,for the purpose of connecting the dis'charge'pipe J with the pipe I andwith an air-chamber, K. From the dome, or it may be from any othersuitable part of the air-chamber, there extends a connecting-pipe, L,which communicates with a mixing-chamber, M, mounted upon a vaporizer orstill, N. Between these two last-mentioned elements of the apparatusthere is a perforated division-plate, O, and be low the imperforatebottom, N, of the still N is a chamber, P, into which is extendedagaspipe, Q, having burners Q thereon, and just above the bottom of thestill there is a blow off pipe and cook, R. A discharge-pipe, S,communicates with the mixing-chamber and with any suitable system ofgas-distribution with which the ordinary burners intended for lightingor heating are connected.

. This being the construction, the operation is as follows: Motion beingimparted to the shaft 13, the piston-head is reciprocated in thecylinder D, and at each downward stroke thereof the inlet-valve D isopened, and air is drawn from the surrounding atmosphere through theopening E into the water-tank and in contact with the perforateddiaphragm thereof, and with the water upon, in, or near the same,whereby the air becomes more or less humid. It is of course understoodthat the water is not allowed tocomeinto contact with the lower ends ofthe pipes F F,lest it be drawn into the cylinder. The outlet-valve D isalso opened at a downward stroke of the piston, while theiulet-valve Disclosed at such stroke, whereby the air taken into the cylinder in apreceding upward stroke of thepistou is forced through the pipe I in thedirection indicated by the arrow, and from thence into the airchamber K,the upper outlet-valve being closed by the pressure of the air thereon,as well as by the suction produced by the downstroke of the piston.Exactly the opposite An opening, E", is formed in the course is taken bythe airin an upstroke of the pistonthat is to say, the valve D isclosed, the valve D opened, the valve 13* opened, and the valve Dclosed-so that at each stroke of the piston saturated airis forced intothe charm ber K, and is held there under compression, except for suchquantity thereof as may pass through the connecting-pipe L into the miXingchamber M. Gas being supplied in the pipe Q to the burners Q, theymay be used in cold weather only for the purpose of heating a desiredquantity of petroleum or other heavy hydrocarbon which is introducedinto the still through the pipe T. The pressure of'air in themixing-chamber produces a thorough commingling of the same with thevapor of the hydrocarbon,whiehrisesinto themiXing-chamher through theperforated plate 0, and when thoroughly commingled the air and gasisconducted through the pipe S to the place of use. Successive charges ofthe h ydroearbon employed are withdrawn from the still through the cockR.

Having described my invention and its operation, what I claim is-- 1. Inan apparatus for carbureting air, the combination of a water-tank havinga perforated diaphragm, pipes terminating above the same, a cylinderprovided with inlet and outlet valves communicating with said pipes andwith a delivery-pipe, an air-chamber, a mixing-chamber, and anoil-chamber, and means for heating the same, these chambers beingconnected with each other, substantially as specified.

2. The combination of the cylinder D with its valves, the pipes F and I,airehamber K, mixing-chamber M, still N, and the gas-suppl y pipe Q Q,substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

ALFRED LANGDON.
